FREDERICK SLOGUM CULVER, OF TAUNTON, MASSACHUSETTS.

SPINNING-MACHINE.

To all whom "it may concern:

Be it known that I, FREDERICK S. CULvnR, a citizen of the United States,residing at Taunton, in the county of Bristol and State ofMassachusetts, have invented a new and useful Improvement inSpinning-Machines, of which the following is a specification.

The present invention has reference to improvements in spinningmachines, and more especially in or relating to the builder motions ofsuch machines.

It comprehends primarily, the production of improved connections betweenthe rockers and the rods which support the thread guide rail, foroperating said rods in unison, and it further includes the production ofdevices associated with the afore-mentioned rods for retaining the guiderail in raised position during dofling.

A structural embodiment of the invention is illustrated in theaccompanying drawings, wherein:

Figure 1 is a fragmental side elevation, with parts in section, of theimproved machine, Fig. 2 is a vertical sectional view taken on the line2 2 of Fig. 1, and Figs. 3 and 4 are enlarged detail views of the twolevers for operating the rail supporting rods.

In said drawings, 5 designates in a general manner the ring rail, 6 thebobbins,

and 7 the drawing rolls from which the threads are led through thethread eyes or pig-tails 8 on the guide rail 9 to said bobbins as iscustomary. The guide rail is secured to pivoted arms 10 carried by theheads 11 mounted upon the upper ends of the vertical operating rods 12,which rods are maintained in position through the intermediary of guides13 and 14 connected to the frame of the machine.

To obtain the desired vertical reciprocatory movement of the rods, thereis provided a series of levers 15 and 16, pivoted respectively, at 17and 18, to bearings or stands 19 and 20, likewise connected to themachine. The first of these levers is pivoted centrally to its stand 19and has one end formed with a series of perforations 21 with which alink 22 is designed for interchangeable engagement, said link beingconnected to one end of a depending chain 23 provided at its other endwith a similar link 24 adjustably connected to the adjacent end of therocker arm 25. The other end of lever 15 has pivoted thereto anupstanding arm Specification of Letters Patent. P t t d 5 14 1911.

Serial No. 572,279.

26 provided with a collar 27 which embraces and is rigidly secured tothe adjacent rod 12. The formation of the several perforations enablesthe leverage to be varied according as may be necessary. The other rod12 of the pair shown is embraced at its lower end by asimilar collar 28fast thereon and provided upon an upstanding arm 29 pivoted to the longor horizontal arm of lever 16, this lever being of the bell crank typeand pivoted at its apex to its stand 20. A connection between saidlevers 15 and 16 is provided in order to insure synchronous actionthereof, and to this end the "short or vertical arm of the latter leveris pivoted to one end of a horizontal rod 30 which is also pivoted atits opposite end to a centrally located upstanding arm 31 provided uponlever 15. There is also connected to the last mentioned end of rod 30 achain or other flexible element 32 which is trained over a suitablymounted pulley 33 and has a weight 34 attached to its free end. Therocker arm 25 is pivotally secured to ;the fitting 41 which is securedto the rock shaft 35 and is provided with the outwardly extending tongue42. The arm 36 secured to the rock shaft 35 carries the usual weight 37for counterbalancing the weight of the ring rail. 1

When the machine is running and the builder motion is, in consequence,in operation, the action of the rock shaft is in effect to bring thetongue 42 in contact with the rocker arm 25'at a predetermined time ofadjustment, so that said rocker arm 25 will move in unison with the rockshaft and will effect .a corresponding actuation of the lever 15 whichwill be transmit-ted in turn to lever 16, as will be apparent, throughthe connecting rod 30. As these levers are actuated, their pivoted arms26 and 29 rise and fall and impart such movements to the correspondingrods 12, whereupon the thread guide rail 9 will likewise be lifted andlowered, so as to cause the guide eyes or pig tails 8 to advance towardand recede from the tops of the bobbins.

The foregoing operation is the same when any number of operating rodsare employed, it being understood that the number of such rods andlevers utilized is dependent primarily upon the length of the frame ofthe machine.

In order to retain the thread guide rail and its pig tails in raisedposition, when doffing takes place, one of the rod heads 11 carries alatch. This latch comprises essen tially a bell .crank lever 38 pivotedto a lug formed on the arm 10 connected to said head, one arm of thelever being enlarged at its end, as indicated by the numeral 39, toconstitute a weight, so that the lever is in effect gravity operated.The opposite arm of the lever is arranged for cooperation with a lug 40formed on the head, the arrangement being such that when the railcarrying arm, and with it the rail, is raised, the second named arm ofthe lever will engage with said lug 40, thereby retaining the said railcarrying .arm 10 and said rail in elevated position.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a spinning machine, the combination, with thethread guide rail, and a vertical rod to which the same is connected; ofa builder motion for imparting a reciprocatory movement to said rodcomprising a lever provided at one end with an arm rigidly connected tosaidrod, a rock shaft, a rocker arm connected therewith, means connectedwith said shaft for operating'said rocker arm and a connection betweenthe other end of said lever and the adjacent end of said rocker arm.

2. In a spinning machine, the combination, with the thread guide rail,and a vertical rod to which the same is connected; of a builder motionfor imparting a reciprocatory movement to said rod comprising a leverhaving an upstanding arm pivoted to one end thereof, said arm beingprovided with a collar rigidly securedto said rod, a rock shaft, arocker arm connected therewith, means connected with said shaft foroperating said rocker arm and a connection between the other end of saidlever and the adjacent end of said rocker .arm.

3. In a spinning machine, the combination, with the thread guide rail,and a vertical rod to which the same is connected; of a builder motionfor imparting a. recipro catory movement to said rod comprising a leverprovided at one end with an arm rigidly connected to said rod, a rockshaft, a fitting secured thereto, a rocker arm pivoted to said fittingat one end and having its other end connected to the other end of saidlever, and a tongue carried by said fitting for operating said rockerarm.

4. In a spinning machine, thecombination with the thread guide rail, anda vertical rod to which the same is connected, of a builder motion forimparting a reciprocatory movement to said rod comprising a leverprovided atone end with an arm rigidly connected to said rod and at theopposite end with a series of perforations, a

rocker arm, and means connecting said rocker arm and the other end ofsaid lever,

said means consisting of a link arranged for interchangeable engagementin said perforations, a link adjustably attached to said rocker arm, anda flexible element connecting said links.

5. The combination in a spinning machine of a vertical rod, a headattached to the upper end thereof and provided with a.

pivoted arm, a thread guide rail secured to said arm, and a latchcarried by said arm and comp-rising a bell crank lever having the end ofone arm weighted, and the other arm arranged to engage said head, tohold said pivoted arm and said rail in elevated position.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
